Abstract

Dargestellt und beschrieben ist eine Ultraschallwellensende- bzw. -empfangsvorrichtung, mit einem Ultraschallwandler (1), einem Ultraschallwellenleiter (2) und einem Mantel (3), wobei der Ultraschallwellenleiter (2) innerhalb des Mantels (3) angeordnet ist, der Ultraschallwandler (1) an einem Ende des Ultraschallwellenleiters (2) angeordnet ist und von dem Ultraschallwandler (1) an diesem Ende des Ultraschallwellenleiters (2) Ultraschallwellen auf diesen übertragbar bzw. von diesem empfangbar sind.An ultrasound wave transmission and reception device is shown and described, with an ultrasonic transducer (1), an ultrasonic waveguide (2) and a jacket (3), the ultrasound waveguide (2) inside the jacket (3) is arranged, the ultrasonic transducer (1) at one end of the ultrasonic waveguide (2) is arranged and by the ultrasonic transducer (1) on this End of the ultrasound waveguide (2) ultrasound waves can be transmitted to it or can be received by it.

Erfindungsgemäß ist zwischen dem Ultraschallwandler (1) und dem dem Ultraschallwandler (1) abgewandten Bereich des Mantels (3) ein Impedanzsprung vorgesehen. Auf diese Weise lassen sich beim Einbau der erfindungsgemäßen Ultraschallwellensende- bzw. -empfangsvorrichtung z. B. in das Meßrohr eines Meßgeräts unerwünschte Kreuzkopplungen stark reduzieren.

Figure 00000001
According to the invention, an impedance jump is provided between the ultrasound transducer (1) and the region of the jacket (3) facing away from the ultrasound transducer (1). In this way, when installing the ultrasonic wave transmitting or receiving device according to the invention, for. B. greatly reduce unwanted cross coupling in the measuring tube of a measuring device.
